Inbreeding and population structure in Montezuma quail. Samples analyzed in this study were mostly unrelated based on (a) kinship analysis. The degree of kinship (solid boxes) between a pair of individuals was based on Waples et al. (2019). (b) Mean individual inbreeding coefficients (F) were significantly higher in the Texas population with no significant difference between Arizona and New Mexico populations. Results from both (c) admixture and (d) PCA clearly demarcate samples from the three collecting sites into independent genetic clusters. However, likelihood estimates indicate the most likely number of ancestral populations in our data is K = 4 (indicated with asterisk), where Arizona is sundered into two subpopulations
